Chapter 4: Atomic theory explains the formation of compounds

Lesson 7: Naming and Writing Formula for Covalent CompoundsYou received 104 questions to practice naming and writing formulas over the break. Those 4 questions were taken from this set of questions. Need more practice? Why not try the other questions... Here's the answer key for you to check your answers.

Lesson 5: Naming and Writing Formula for Ionic CompoundsToday in class you worked in groups of three to complete an activity on naming ionic compounds.

Lesson 4: Forming Compounds- Textbook pages 176 - 180Today in class you saw how Bohr models and Lewis diagrams can be used to show the different types of bonding between atoms. Here are some slides used in previous years, explaining how to draw Lewis diagrams for covalent compounds.After the lesson, you used Fruit Loops to see how electrons are transferred or shared to make ionic and covalent compounds respectively. "Loopy" Lewis Diagrams

Lesson 1OK, so -- what's an atom and what does it have to do with molecules? Let's talk tiny, and I mean really itty-bitty. ATOMS are the basic building blocks of everything you can see around you, and even lots of things you can't see, like the air that you breathe. Atoms are so small that there are millions and billions and trillions in the tiniest speck you can see. Solids, liquids, gases - all matter - are made up of atoms (or other things, like molecules, that are made from atoms)! Click here to read more...
